Patented May 15, 1934 UNITED STATES PATENT: OFFICE MACHINE FOR MAKING LAMP SHADES AND THE LIKE 17 Claims.

This invention relates more particularly to a machine for making lamp-shades and the like, and the main object of the improvement is the provision of a machine of the said character to form alternate transverse arcuate flutes or plaits on strip-material which is then cut into desired lengths and joined annularly by its end-flutes or plaits with either the concave or the convex edge of the flutes or plaits exteriorly thereof to form frusto-conical-shades of either the concave or the convex appearance.

Another object of the invention is, the provision of a machine with which lampshades of the said character may be economically produced from strip-material, which machine includes, means for supporting one or more rolls of strip material for producing one or more webs of single or multi-ply strip or strips, guided, and fluted or plaited by the machine continuously, means for impregnating, dampening, or adhesive applying for one or more of the said strips, as the strip or strips are fed thru the machine, and means for applying a metal or other shape retaining binding at the longitudinal marginal edges of the strip or strips, as the latter are fluted or plaited by the machine. Said marginal binding makes possible the assembling of the lampshade of the said character, without the employment of an auxiliary-frame.

Other objects will be apparent, as the description proceeds.

Fig. 23 shows a form of lampshade of the convex-rectilinear type, when the prefolded strip of Fig. 14, is transversely fluted or plaited by the roller-variation shown in Fig. 16.

Referring now to the drawings, 1 denotes an arch-like frame piece formed with two diametrically opposed standard members 2, 3, having alined bearing-seats 4 and 5.

A fluting or plaiting roller 6 preferably formed with a heat-receiving chamber '7 which communicates with hollow axes 8, 9, which may be fastened to said roller, or formed integral therewith, as illustrated. Said axes rotate in tubular bearings 10, 11, which are held in said seats, by bearing-blocks 12, 13, reinovably secured to said standards, as at Figs. 1 and 2. In the preferred embodiment, roller 6 has a substantial elliptical circumferential periphery which narrows towards the axis thereof, and is formed with series of diametrically spaced longitudinal convex teeth or ridges 14 of approximately V shape cross sectional form which varies width and height from point 15 at the wider circumferential portion, to points 16 at the narrow ends of the roller. Said teeth or ridges are intermediated by similarly shaped, and dimensioned longitudinal convex grooves 17 (see illustration in sheet 1).

Cooperating with roller 6, are a pair of frustoconical rollers 18 having a circumferential concave periphery formed with series of diametrically spaced longitudinal concave teeth or ridges 19, intermediated by similarly shaped longitudinal concave grooves 20, which are equally dimensioned as the teeth or ridges and grooves of roller 6. And each roller 18 is rotatably supported in a manner that its narrow end is in mesh with the relative narrow end of roller 6, while the wider end of said rollers are tangent and in mesh with the wider circumferential portion of roller 6, as at Figs. 1 and 5. Axially mounted thereon or integrally formed with rollers 18, are shafts 21, 22. The latter rotate in tube-bearings 23 which are held slidably in slots 24 formed at the oblique portions 2A of the frame-piece, while axis 21 of the rollers, rotate in tube-bearings 25 which are held slidably in slots 26 formed at the inwardly inclined portions 27 of an approximately triangular bracket element 28 which is removably secured underneath the apex of the frame-piece, as'at 29. (Jo-operating with bearings 23, are springs 30 which are held in place by studs or bosses 31 secured at the base of slots 24, and said springs abut against the underside of said bearings urging that end of the rollers away from roller 6.

Bearings 25'have similar spring arrangements, as that described in conjunction with bearings 23, for urging the seccnd end of the rollers in a similar manner. Co-operating with said two pairs of bearings in opposition to said springs, are screws 33 threaded on the frame-piece and which extend downward toward the respective bearing. Said screws have a pointed end received by a recess 34 formed on said bearings, as at Figs. 1 and 9." Inserted on axes 8, 9, of roller 6, are collars 8A, 9A, (one of which is shown in Fig. 8) formed with 'a beveled-head which closes part of the end-teeth or ridges, and end grooves of said roller, to prevent lateral movement to the stripmaterial, while the latter is being fluted or plaited. The above described rollers may be rotated in any desired manner, as shown. I provide a shaft 35 keyed as at 36, to axis 8 of roller 6, closing that outlet of chamber 7. Said shaft carries a cone-shape pulley 37 which may be linked by a driving belt (not shown) which may be connected with a similar pulley driven by any convenient source of power. heated by any convenient heat-source, as shown. I provide the same with a gas-conduit or pipe 38 supplied from a gas-main (not shown), said pipe supported on standard 3, has an elbow-joint 39 which supports a horizontal pipe-section 40 centrally thru axis 9, to the interior ofthe chamber. The end of pipe section 40 is closed to force the escape of the gas thru jets 41 from which it is burned to heat the chamber. The latter may be formed with additional air outlets, besides the outlet thru axis 9, by forming small bores at convenient points thru the circumferential wall of the chamber. Secured to standards 2, 3, are side-frames 42, 43, each formed with a pair of legs 44, 45. The side-frames are also supported in spaced position in line with standards 2, 3, by transverse ties or rods 46. Formed at the rear end of the side-frames are alined bearings 47, 48, 49, each pair of which supports a transverse shaft 50 having shouldered ends 51. Adjustable on said shafts are side-flanges 52 which may intermediate one or more rolls of strip-materials 53, 54, 55, supported by said shafts.

Associated with the latter may be frictionbrake elements (not illustrated) which retard the unwinding of the strip-materials. Situated below rolls 53, 54, inwardly to legs 45 of the sideframes, is a fountain or pan 56 which may be of any suitable construction and which may contain dampening, impregnating, or adhesive liquids, which may be applied to one of the stripmaterials, by means of conveying-rollers 57, 58 and 59, which may have any suitable arrangements. Rotatably supported on the side-frames and in line with the meshing-point of the fluting or plaiting rollers, are two pairs of strip-material pressure and tension-regulating rollers 60 and 61.

The upper-rollers of each said pairs have friction-bushing portions 62 which are acted upon by set-screws 63, to regulate the pressure of said rollers against the strip-material fed therebetween.

Supported by the side-frames are also a plurality of transverse rods 64, which support sideflanges 65 adjustable longitudinally thereon. Adjustable on said rods are also intermediary segmental flanges 66 (see Figs. 3 and 10) which are formed with diametrically opposed hub-portions cut away longitudinally as at 6'7, 68, to expose the surface of the rods whereupon the stripmaterial travels transversely of the rods. Said segmental-flanges are also adapted to be adjusted in an inoperative position with the segmental flange below the traveling line or plane of the strip-material when the latter is of a width to take up the entire width capacity of the machine. Formed mid-way of the side frames above legs 44, are recesses 69, at the inner side of which are ledges 70 which support a cross-bar or bed 71. Spaced longitudinaly on said bed and secured thereto, are dove-tail forming plates 72, '73, which form a dove-tail groove longitudinally on said bed. Standards 74, '75, are each formed with a dove-tail foot-portion received by said dove-tail groove. Formed on said recesses of the sideframes and in line with said dove-tail groove, are projections or ears 76, 7'7, formed with a threaded bore, each to receive a screw-rod '78 equipped Chamber '7 may be with a securingnut 79 threaded thereon, and each of said screw-rods is individually swiveled at the foot of corresponding standard, as at 80, Fig. 11, so that the standards may be individually adjusted along said dove-tail groove. Supported by said adjustable standards, are tables 81, 82, which support vertical studs 83, 84.

Rotatable on studs 83 are binding strip-guiding rollers 85 which are formed with a circumferential V shaped groove 86, removable flange 87, and replaceable or auxiliary sections 88. The latter serve to variate the length of the said rollers to accommodate different widths of binding strip material to be guided between the flanges of said rollers. Formed on studs 83 are spaced transverse bores 89, to receive a pin 90 in any one of said bores, according to the composite length of said binding-guide rollers. Tables 81, 82, have an inward projecting portion 91 formed with an elongated slot 92, each to receive a vertical pivotscrew 93 formed with a beveled head 94. The latter rests in a countersunk portion of axial bores 95 of binding strip-scoring rollers 96 which are rotatably supported by said pivot-screws which are equipped with securing nuts 97, 98, to bolt said screws in adjusted positions in slots 92, toward and from rollers 85. Rollers 96 are formed with a beveled head 99 having a substantial sharp circumferential edge 100 which rotates in the groove 86 of rollers 85. Rollers 96 may also have auxiliary sections 101 to adjust the same, according to the adjustments of rollers 85, so that edge 100 is constantly in a rotative relation with the relative roller 85. Rotatable on studs 84, are binding strip reel plates or flanges 102, to support a spool of binding 103, which may be of metal or other strip-material binding. Secured on said studs, above said spools, are flanges 104 to keep the spools rotatable and in line with rollers 85, so that the binding strip may be scored by edge 101, as the binding strip is fed between said pairs of co-operating rollers. (See Figs. 3 and 11.)

Associated with the forward end of the machine, may be a reeling mechanism (not shown) which may be of any suitable construction, and supported by arms 105 which are only fractionally illustrated, in Figs. 1 and 2, as being supported by standards 2 and 3, of the frame-piece 1. Said reel, as obvious, is intended to coil up the fluted or plaited strip or strips in a loose manner, and the reel may be driven from the shaft of roller 6, in any suitable manner.

The modification of the fiuting or plaiting rollers shown in illustration Fig. 16, consists only in the variation of the form of the longitudinal grooves of roller 6A which are rectilinear as at 17A, instead of convex, as in the main description. While rollers 18A are formed with teeth or ridges 19A having rectilinear edges instead of arcuate or concave, as in the main description.

Said variation, however, embodies the same principle, that of permitting the narrow ends of rollers 6 and 18, respectively, to take up same length of strip-material, as the wider circumferential point of the rollers during the fiuting or plaiting of the strip, so as to prevent throwing the strip against the sides of the machine, as it would result, had the ridges and grooves of the rollers been formed without longitudinal dimensional variation, as hereabove provided for. Consequently, without the said dimensional ridges and grooves variation, it would necessitate blanks of material cut in the form of a sector of a circle, in order to form thereon, arcuate transverse flutes or plaits, and. as obvious, this latter mode of production, will eventually increase the cost of this type of lampshade considerably, due also to the waste of the material from which the sector-blanks are cut. At the same time, the roller variation shown in dotted illustration Fig. 16, is capable to produce lampshades whose exterior decorative appearance is the same, as in the invention embodied in this specification.

While the function of the parts composing this machine have been outlined along with the description, I will now explain a general operation.

Assuming that the composite strip-material A is formed by three superposed strips B, C, D, pulled from rolls 53, 54 and 55, I feed the strips as shown in Fig. 2. Then advance the compositestrip and insert the same thru pair of rollers 60, and by rotating the same from hand-wheel A which is keyed or otherwise secured at an endshaft of one of the rollers, advance the stripmaterial between flanges and 66, thence between rollers 85, above rollers 96, between flanges 65, 66, and thru pair of rollers 61. Then insert the binding strip thru the guiding and scoring rollers, as at Fig. 11, and flatten the same against the strip, which, when it has passed thru pair of rollers 61, said marginal binding will be well pressed against both marginal longitudinal surfaces of the strip. The bound strip is further advanced by manipulating hand-wheel 61A which is secured at an end shaft of one roller of said pair, thereby moving the bound strip forward between flanges 65, 66, thence thru the fiuting or plaiting rollers in a manner well suggested in Fig. 3.

It is obvious, that if a second similar strip is fed thru the machine at the lateral longitudinal side of the above described strip, the strips could be bound only at the outer longitudinal margin thereof, because only two margin-binding applying devices are here provided. This, however, is not to be taken as indicative that this machine is limited to only two of said mechanisms, or that only two strips at a time may be fed thru this machine. Said parts may be duplicated so as to bind and feed more strips if desired.

The arcuately fluted or plaited strip or strips, may be coiled up by means of a reel, as hereabove referred to, and the shaped material is then cut into desired lengths (one of which is illustrated in Fig. 19) which represents a portion of the strip fluted or plaited thru a longitudinal half of fluting or plaiting roller 6, and one of the cooperating rollers 18. Said fluted or plaited blank when joined by its end flutes or plaits, will form the lampshade illustrated in Fig. 18, when the convex edges of the flutes or plaits are exteriorly, otherwise it will form the lampshade shown in Fig. 17. Few other examples of the several lampshade-shapes which this machine is capable to produce, are shown in dotted illustrations, of which, the one shown in Fig. 20, is formed by feeding the strip-material thru the middle of roller 6, score the fluted or plaited strip on its longitudinal center E, and annularly join the same with the convex-edges interiorly thereof, after which, one or both ends of the lampshade may be contracted in any tapered degree, because the type of arcuate flutes or plaits produced by the machine herein embodied, may be contracted or expanded, because the dimension thereof, from the lower to the upper edge of the flutes or plaits, is of the same width throughout their arcuate length.

As obvious, by assembling the lampshade of Fig. 20, inversely, I produce a lampshade of a substantial globular exterior appearance.

Ihe forms of lampshades shown in Figs; 21 and 22, are produced by fiuting or plaiting .a stripmaterial having a longitudinally folded portion F, as at Fig. 14. As obvious, when the strip fluted or plaited as such, as annularly joined with the folded portion expanded outwardly circumferentially, .the edges of the flutes or plait portion of the folded portion; will be inverse with the edges of the upper portion, thereby producing both concave and convex appearances.

The lampshade shown in Fig. 23, is formed with a similar strip, as Fig. 14, when the same is fluted or plaited by the roller-variation of Fig. 16. In this it will be seen, that the exterior edges of the flute or plait portion of the folded portion G, will be the same as the interior edges of the upper portion which are exteriorly convex, as at H.

In whatever form, when the strip is marginallybound, especially with a metal binding, the usual auxiliary wire-frame will result unnecessary for supporting a lampshade of the above described construction, and that a simple lamp-bearing fixture fastened at one end of the lampshade, is all that will be required for the complete assembly thereof.

While in the described embodiment I have outlined that the flutes or plaits are of V shape, it is to be understood, that my invention is not limited to said shape.

Also it is apparent, that I can produce similar lampshades with the use of reciprocable elements, instead of rotary, as described.

The said reciprocable elements may be formed with similar ridges and grooves of the concave convex form, as in the described rollers.

Though, as obvious, the latter are designed for a considerable more rapid production, than it would be possible with fluting or plaiting elements of the reciprocable or alternate form.

In the foregoing description, I have embodied the preferred form of my invention, but I do not wish to be misunderstood as limiting myself thereto as I am aware that modifications may be made therein Without departing from the principle or sacrificing any of the advantages of this invention, therefore I reserve to myself the right to make such changes as fairly fall within the scope of the claims.
